IIS file/folder Permissions CS2008

Are these the correct file/folder permissions for cs2008 using the highest security and still have everything function properly?

/ asp.net r/e
/ auth read only
/blogs/ asp.net full
/SiteFiles/ asp.net full
/filestorage/ asp.net full
/Utility/RankIcons asp.net full
/Utility/RoleIcons asp.net full

Thanks!

 I think in CS08 the requirements are only -  read for everything except for the filestorage folder which should have modify.  If you plan on having a lot of blogs, and would like users to be able to access their blogs in the format http://yourdomain.com/blogs/A_Blog/ instead of http://yourdomain.com/blogs/A_Blog/default.aspx, then you'll either have to give CS Write permission to the blogs directory - this is becuase it needs to trick IIS by creating an empty default.aspx file.
